Answer:

54

Step-by-step explanation:

75% of 72 is 54

Answer:

96

Step-by-step explanation:

72 is 75% of 96.

72 ÷ 75% = 96

Step-by-step explanation:

x²+2x+1

x²+x+x+1

x(x+1)1(x+1).

(x+1)(x+1)

x=-1. , x=-1

Answer:

[tex]\displaystyle \boxed{\text{\sf \Large x=-1}}[/tex]

Step-by-step explanation:

Add 1 to both sides

[tex]x^2+2x+1=0[/tex]

Use quadratic formula with a=1, b=2, c=1

[tex]\displaystyle x=\frac{-b \pm \sqrt{b^2-4ac} }{2a}[/tex]

[tex]\displaystyle x= \frac{-(2) \pm \sqrt{(2)^2-4(1)(1)} }{2(1)}=-1[/tex]

Answer:

[tex]7[/tex]

Step-by-step explanation:

This means that there are 20 terms in between 11 and 31

[tex]31-11=20[/tex]

Since we know that the [tex]11th[/tex] term is [tex]29[/tex] and the [tex]31st[/tex] term is [tex]169[/tex], you can subtract the two to find out the values in between

[tex]169-29=140[/tex]

Now all we have to do is divide the values in between by the number of terms to find the common difference.

[tex]\frac{140}{20} =7[/tex]

Therefore the common difference is  [tex]7[/tex]

Answer:

sup(x,3)

Step-by-step explanation:

Linear equation:

A linear equation has the following format:

[tex]y = ax + b[/tex]

In a linear equation, when x changes by 1, y will always change by the amount a, which is called slope.

In this question:

y=sup(x,3)+2x+1

[tex]y = 2x + 1[/tex] would be a linear equation.

However, the expression sup(x,3), that is, the higher value between x and 3, means that the function is not linear.

Answer:

Z = 8.4

Step-by-step explanation:

Jusg move 6.3 behind

When something negative moves behind it becomes positive

So 2.1 plus 6.3 is 8.4

Answer:

Z=8.4

Step-by-step explanation:

1. Add 6.3 to both sides.

Z =2.1+6.3

2.Simplify 2.1+6.3 to  8.4

Z=8.4

--------------------------(Checking answer)

Z−6.3=2.1

1. Let Z=8.4

8.4-6.3=2.1

2. Simplify  8.4-6.3 to  2.1

2.1=2.1

Answer:

32

Step-by-step explanation:

8/1/4=8*4=32

Answer:

32

Step-by-step explanation:

1/4=0.25.

8/0.25 = 32

The area of the land is 1250 square meters.

What is the area of the rectangle?

To find the area of a rectangle, we multiply the length by the width.

So the formula for finding the area of the rectangle is

Area = Length * Width

In this case, the land is 25 meters wide and 50 meters long, so the area is:

Area = length × width

Area = 50 m × 25 m

Area = 1250 m²

Hence, the area of the land is 1250 square meters.

Answer:

h = 18.88 inches

Step-by-step explanation:

Given that,

The circumference of a cylinder is 20 inches

The volume of the cylinder, V = 600 cubic inches

We need to find the height of the cylinder. We know that the volume of a cylinder is given by :

[tex]V=\pi r^2h[/tex]

r is radius

We know that,

circumference = 2πr

[tex]r=\dfrac{C}{2\pi}\\\\r=\dfrac{20}{2\pi}\\\\r=3.18\ \text{inches}[/tex]

So,

[tex]h=\dfrac{V}{\pi r^2}\\\\h=\dfrac{600}{\pi\times (3.18)^2}\\\\h=18.88\ \text{inches}[/tex]

So, the height of the cylinder is 18.88 inches.

Answer:

253cm²

Step-by-step explanation:

Area of the trapezoid = 1/2(b1+b2)*h

Given

h = 22cm

b1 = 10.5cm

b2 = 12.5cm

Substitute

Area of the trapezoid = 1/2(10.5+12.5)*22

Area of the trapezoid = 1/2(23)*22

Area of the trapezoid =11*23

Area of the trapezoid = 253cm²

Hence the area of the trapezoid is 253cm²
